This is my 3rd paragraph, what corrections need to be made?

In my life I have diverted many opportunities, tasks, and events because they involve talking. I even made important decisions based on if it involved socializing or not. My past actions were proven to be wrong and In fact I just dug myself in a deeper hole. They stopped me from growing and I just went back to square one. I had taken the wrong path because of my fear of talking to people. In the third grade, I left a stack of important doents in the bathroom, because I was too scared to give to the counselor. I later got in trouble for not fulfilling my duty. As the years went by my consequences intensified. In my seventh grade math cl, my teacher forgot to give me an important ignment; I wanted to tell her, but I could not. I made several attempts to confront my teacher about the issue, but I always chickened out at the last minute. At the end of the day, I received a 0 for my “uncompleted” worksheet. I was angry at myself I did not have the strength to do a task that would be incredibly simple to everyone else. My grade dropped down because of that zero and it took awhile to bring it back up. What saddens me is that the whole situation could be avoided if I just talked to my teacher. In eighth a school dance was coming up and I wanted to ask out my crush, Jada. It seemed to be an impossible feat according to my peers, but I was determined to ask her out. I practiced for weeks on end, creating clever jokes and constructing a bullet proof conversation starter. Finally it seemed I was ready to ask out Jada, but I hesitated and postponed it for another day. Then I postponed for another day and then another day, well you get the picture. By the time I was ready to ask out Jada, I found out she was going out with someone else. I missed out on a chance of a lifetime because I was scared to talk Jada. I have let shyness run my life ever since then, and it has given the same negative results. I was scared to shot and let go of the chains that held me back. I’m trying to let everything go and chase after my dreams without my shyness weighing me down.
